Data flow refresh using web connector fails with invalid credentials



I installed the power bi gateway and created a data source using the web connector. When creating the data source, I gave it a name and the URL and configured as anonymous authentication.


When creating the data flow, I tried to use the name of the data source but it doesn't work, the web connector requires the URL again. Ok. Data Flow created.


However, I can't refresh the data flow, it always results in authentication error, the message is "Data source credentials are missing or invalid. Please update the credentials for Web in dataflow". I can't identify if the error is between the portal and the gateway or the gateway and the web site. 

The URL itself I can import if I use power bi desktop directly and it event work during the creation of the data flow, but not the refresh. How to troubleshoot this?


Thank you!

If just use this credentials to create a report and check if it could refresh in power bi service.
